SCREEN- FRAME.

SPECIFICATION forming part of Letters Patent No. 397,797, dated February 12, 1889.

Application filed April 20, 1888.

T0 aZZ whom it may concern.-

Be it known that I, HIRAM F. HALL, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Automatically-Adjustable Screen- Frames and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the lettersof reference marked thereon,whieh form part of this specification.

My invention relates to that class of screenframes which are provided with extensible side bars held normally projected by springpressnre and provided with caps at their ends for guiding the said bars in their movements.

The objects of my invention are to provide such screens with means for covering the ends of the screen-frame and side bars, so as to not only properly guide the movements of said bars relative to the frame, but also to permit the bars to automatically adjust themselves to accord with irregularities in the windowcasing due to unequal settling of the building, and under all circumstances to form a perfectly dust-proof guard for the spaces be tween the screen-frame and the casing.

To the above purposes my invention consists in the peculiar and novel features of construction and arrangement hereinafter described and claimed.

In the drawings, Figure l is an elevation of the rear side of a complete frame and screen. Fig. 2 is an elevation of the front side of the same. Fig. 3 is a detail transverse sectional view through the window-frame and screen, showing the screen upon the inside parallel with and in close proximity to the lower sash. Fig. at is a like view showing the screen upon the outside of the window in like relation with the upper sash. Fig. 5 is a detail transverse sectional view of a portion of screen-frame with the adjustable side and the guide upon the window-easing, this figure being drawn on an enlarged scale.

A designates the inner side of the windowcasing, having ways B attached thereto, prefany necessary expansion.

erably upon the outer and inner sides of the window-casing.

D represents the screenframe, having side bars, 0, adj ustably attached thereto and held in position by metal corner-pieces .1, attached to the ends of the side bars and moving upon the screen-frame Side bars, C, are made with a portion cor responding in thickness with the outer edge of the screen-frame, and which is in parallel relation therewith when in position, and a right-angled wing portion, 0, to overlap the space between the edge of the frame and the portionO' of the side bar when adjusted to The corner-pieces are preferably constructed of sheet metal, and are of the same form in cross-section as the screen-frame and embrace a portion of the same by their sides, the top portion closing the space between the side bar and frame.

E represents a stay and retainer attached to the side bar by screws or nails, and held to the frame by a screw or nail, G, passed through a slot, F, in the stay and retaining-piece E, the slot being preferably formed by-cutting a slit longitudinally of the stay from the center to near each end, and then turning the edges at an angle to strengthen the stay and render it more rigid.

H is the wire screen, secured to the frame by strips 11 in the usual manner.

K designates springs attached to the frame by screws or nails K and bearing against the parallel sides 0 of the side bars, and serving to adjust the side bars to closely fit between the sides of the window-casing, having a great scope of expansion or contraction with relation to the screen-frame by reason of the wings O and the corner-irons. For convenience in raising the screen, and also for contracting the sides, perforations J are formed in the screen and bars, respectively.

In. operation ways B are permanently secured to the window-casingpreferably on the inner and outer sides of the window-casing. Bars 0 are adjustably connected with the screen-frame and become a part thereof. To insert the frame the side bars are moved inwardly to allow the bars to pass the projecting sides of the ways and are allowed to spring i-ntothe grooves. Should the easinghe out of a true line or oi an irregular width, the side bars eompensate for the same by the greater or less expansion ol. the upper or lower spring or springs, and the frame (whieh gen erally embraees the sereen-l'rame and side bars) can he moved up or down in the ways, always titling closely therein by reason of the action of the springs. The frame is rendered interchangeable from the outer to the inner side of the window by reason of the :lati'ility with which it can he removed from the inner and inserted into the outer ways. This feature is 01: great value, as by this means when it desired to ventilate from the upper portion of the window the sereen can he placed on the inside of the room, thereby prevtmting llies mosquitoes, &e., from entering between thesame when moved from a normal. position; or, if desired to raise the lower window-sash, the sereen isplaeed upon the outside with the same effect.

lly reason of the adjust ability of the frames they can heconstructed as an artiele of manut'z'ietnre and sold to the trade, and can he adjusted in. plaee without req l'iiring the aid of skilled lahor.

\Yhat I elaim is '1. An automatically adjustable screenframe comprising a rcaetangnlar sereen-trame, side bars held in parallel relation therewith, and em-ner-pieees having winged portions secured at eaeh side of the sidebars, andwhieh overlap and mnln'aee the frame upon each side thereol, in eomhination with springs interposed between the screen-frame and side hars, as and for the purpose set t'orth.

2. As a new article of m zimu'faeture, a screenframe eonsisting of a rectangular frame hav-. ing a sereen attached thereto, side hairs having a portion parallel with. the sides of the frame and an overlapping wing portion, springs inte'r iosed between the side bars and frame, guides secured to eaeh end ot' the side 'l;)ars,whieh cover the ends of the side bars and the eorners oi the frame, and a central. stay and retaining-piece connected rigidly to the bars and movahly lo the Frame, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I hereby atiix my signature in pres enee of two witnesses.
